CHAPTER 1
INTRODUCTION
1.1 About the
Multimeter
Large consumers of electricity e.g. factories, hotels, hospitals,
municipalities, need to know the history of their consumption and
the quality of the power supply. Details such as Voltage, Current,
Power Factor, Hertz, Neutral Current, Energy Demands and all
electricity related events are recorded in the
.
An additional feature of the Multimeter is the ability to measure
Harmonics. Part of the Electricity Supply Authority’s bill reflects
poor or good Harmonics in the consumer’s system, therefore it is
in his interest to monitor Harmonics and try to improve it.
These are all recorded on a continual basis and can be recalled
and shown on the front panel display of the instrument with a few
simple key-strokes any time the user wishes.
The
is a compact, multi
functional, three-phase Multimeter simple to install and is
especially designed to integrate into Building Management
Systems. It requires no special mounting and is ideally suited for
mounting on the front face of any standard electrical panel.
The Configuration and Setup is menu driven, with password
protection.
Communication with external devices is simple and is based on
standard known technology.
The
boasts a new
innovative built in “Flash Memory”, which pioneers a new
frontier into electrical measurement. It has a 1 MB of FLASH
5
MEMORY with a capacity of recording up to 2 years of power
malfunctions and interruptions.
Readings, graphs, tables & history are shown on the graphic
display of the
This
display is a state of the art screen with a resolution of 160X128.
Each
is carefully and
meticulously manufactured using quality components and the
latest production methods. Before leaving the factory each
is calibrated and sent to
the customer accompanied by the test certificate and Certificate of
Compliance (C.O.C).

Communication Connections
The
supports RS232
and RS485. Connections for both are provided on the Rear Panel,
(see Figure 6.1) and are made by means of the connectors
provided. The same information can be transmitted along both,
but only one at a time. The user can choose the one that best suits
his current situation and equipment.
The 10 BASE-T sockets support a standard connection to any
Ethernet network.
Figure 9.1. Communication Connections
9.2 Communication Settings
To enable the User connecting the
to a PC master computer for successful
communications, the Communication Setup parameters of both
must match; i.e. the port of the PC master and the configuration
settings of the Power meter.
76
9.3
Address
Each Power meter in a communication system must have its own
unique address.
Since the
works on
MODBUS, the available addresses are from ‘1’ to ‘247’.
9.4
Baud Rate
The Baud Rate is the communication speed in Bits per second
(BPS) that the
communicates with the PC master. The better the communication
line Quality, the faster the communications may be.
If the communication line is routed through a “noisy”
environment, it may be necessary to decrease the Baud Rate.
